The Stoddard report shows this:

Testing: Substantial time and investment has already been spent on extensive surface and drill testing, bulk sampling and assays. Over 160 test sites have been sampled and assayed on the
properties. “The results of exploration and development work carried out on the Gold Star properties have shown conclusively that substantial quantities of free gold are contained in both the stream channel and hi-bench placer deposits.”

What I am wondering is why they are testing and assaying the claims again when over 160 tests have already been done? I thought samples and assay results were preserved somewhere and these would be available. Am I wrong - they are not saved??
